Improved Subroutine Efficiency
Through Calling-Sequence
J
Modification*
MARK H. ELFIELD Ohio State University, Columbus, Ohio
and
CHARLES E. COHN Argonne National Laboratory, Argonne, Illinois

Improvements in subroutine efficiency are sometimes possible through replacement of the calling sequence by instructions which do all or part of the subroutine's job. A number of FORTRAN-callable subroutines have been written to implement this concept.
In present programming practice, the calling sequence for subroutines has become standardized. With minor variations, it consists of a save-place-andbranch instruction pointing to the subroutine entry, followed by a series of words containing the argument addresses. We have found that some efficiency gains are possible if the words in the calling sequence are replaced by instructions which do all or part of the subroutine's job. The replacement is done by the subroutine the first time it is called from a given i, location.
Our implementations of this concept have been done on computers whose word length .is sufficient to carry any operation code in association with the address of any location in memory (i.e. the 24-bit-word Honeywell DDP24 and Systems Engineering Laboratories SEL-840) . Some of the ideas may not be applicable to shorter-word machines that do not have this capability.
0 Work performed under the auspices of ~Y~ the U.S. Atomic Energy Commission, in
part under Contract No. AT( 11-1)-1545 r'! for the Chicago Operations Office.

A simple example is a FORTRANcallable two-argument integer function subroutine whose result is the bit-bybit logical product of the · arguments. Before execution, the calling sequence for this function contains the following three words:
1. Save place-and-branch to the subroutine
2. Address of first argument
3. Address of second argument.
On entry, the subroutine replaces the above with the following:
1. Load-accumulator instruction addressed to first argument
2. No-operation instruction
3. And-to-accumulator instruction addressed to second argument.
In the process, any index tags and/ or indirect flags associated with the argument addresses are carried over to the respective instructions. This takes care of cases where the arguments are subscripted variables, dummy variables or arithmetic expressions. The nooperation instruction is included just to fill up space.
After performing these substitutions, the subroutine transfers control to the first instruction in the sequence. On subsequent passes, the sequence is executed in-line with no further reference to the subroutine. Such execution saves six memory cycles out of eleven over the tightest-possible conventional

subroutine coding on the DDP-24. Similar routines have been written for logical-sum and exclusive-or operations.
The concept is particularly well suited to intrinsic functions in FORTRAN. Sophisticated compilers often implement such functions with in-line coding. However, compilers for smaller computers usually resort to subroutine calls because of memory size limitations at compile time.
An example is IABS, integer absolute value. Its calling sequence has the form
1. Save-place-and-branch to IABS
2. Address of argument.
For machines with sign-magnitude arithmetic, the above may be replaced by
1. Load-accumulator instruction addressed to argument
2. Masking instruction to drop sign bit.
On the DDP-24, it takes 4 memory cycles for each execution after the first, compared to 10 for optimal con-. ventional coding, and 17 for the existing library subroutine. For a machine with a suitable instruction set, still another memory cycle may be saved by the sequence
1. Clear-accumulator instruction
2. Add-magnitude instruction addressed to argument.

System Design Via On-Line Simulation
By Herman A. Fischer

Evolution of Real Systems
Real-life industrial systems generally evolve with time. A general scheme of the steps comprising the evolution of real systems (e.g., engineering systems, economic systems, transportation systems) is given in Figure 1.
One notices that the steps following (d) and (g) require the systems analyst to wait and observe how the system reacts to its environment. This implies that as the operating environment changes, the system is generally behind the times and is not optimal in performance. Consider what happens, however, if system evolution can be accelerated with respcet to time: the system can then be modified rapidly so that it can meet its demands with greater effectiveness. One method of achieving an acceleration of evolution is to create a model of the system and its environment. Simulated environmental pressures can then be applied at an accelerated rate, and the effects on the system can be determined.

Herman A. Fischer received a B.S. in physics in 1968 from the UniversVty of California at Los Angeles, and has completed course work at UCLA for an M.S. in engineering. Prior to joining Computer Processes, Inc. in 1968, Mr. Fischer was employed by International Business Machines Corporation where he specialized in simulation applications.

cannot expect more than two or three exercises of the model per day. An average system study may require 10 to 100 iterations of a model, and a few weeks of debugging the model, before a useful set of results is obtained. Thus, batch-processing of a simulated system is a rather time-consuming process, and the performance of the analyst as well as the evolution of the system may be degraded since the modeler may conceive of an idea or the effect of a parameter change, and then lose his train of thought as a result of being forced to wait for computer turnaround.

NORDEN,1 are highly versatile (in an on-line sertse), especially those which use GPSS as the basic simulation tool. However, most observers still consider on-line simulation prohibitively expensive for use as a standard technique. The successful on-line GPSS-based simulation tools are easy to use, although they are slow in running speed and are expensive. This paper differs from previous work in that we will point out that the technique of on-line simulation can be applied successfully with all the previollsly suggested features at costs comparable to those incurred conventionally.

ging of a computer model. The modeler can request a change or modification in
one or more parameters of the simulation. This parametric variation is accomplished by changing system parameters (permanent entities in Simscript; static structures in PL/ I and PL/ I: SL) and attributes of temporary entities. When debugging a simulation program by this method, one can correct a value that is in error and continue the simulation. When exercising a model, this type of parametric variation aids evolving or optimizing the system.18

Whereas in GPSS the change can be accomplished during simulation, in PL/ I: SL the change requires stopping the simulation, making the correction to the proper subroutine or process procedure (s), recompiling that procedure and re-link editing the model. (This takes a minute

simplify the job control language requirements. The proper use of libraries of link-edit modules on disk aids is to assemble previously compiled procedures and overlays for the link-edit step. A compilation need only delay the online user a minute or so, rather than preclude his use of the computer during a scheduled time period. Thus, the capability exists in batch processing languages to make on-line changes, although the procedure for this is not as elegant as GPSS's change block since it requires re-starting the simulation. (Note that a PL/ I:SL simulation ought to require less time to restart than GPSS due to the slower interpretive nature of GPSS.)
An additional feature which might be desirable in online simulations, is the ability to alter the time status of the simulation. That is, it might be desirable to be able to backtrace the simulation to re-observe a simulated event or to observe the effect of altering a parameter and retracing over a portion of the simulation. This would be very valuable in debugging where one retraces and then requests additional reports and trace printouts to locate a bug. Backtracing can be provided for a simulation study in any

( l) Change the duration of time simulated per interaction cycle.
(2) Stop the simulation for detailed observation. (3) Permit communication between modeler and model
of the form: (a) Change of one or several parameters. (b) Change or modification of an element of the

(4) Permit communications between the modeler and a stored program. I.e., permit the modeler to write a sub-routine to do something on his command or request.
Summary
Digital simulation has traditionally been carried out off-line within a batch-processing environment. In this paper the feasibility and practicality of conducting digital simulation on-line is discussed. We have considered the computer systems aspects of going on-line, specifically in terms of the IBM System/ 360 and its PL/ I language, and have also considered the economics of so doing. The benefits to the modeler of on-line simulation have been pointed out. In conclusion, it appears that on-line simulation ( l) is of considerable benefit to the modeler; (2) can be installed within the modern multiprogrammed, batchprocessing environment without a major effort in terms of time and cost; and (3) can be operated at programmermachine costs comparable to those of conventional, offline simulation.

Reducing The Simulation Credibility Gap
Richard A. Kaimann °

It has been said that the computer is one of the few

inventions that has enabled man to expand his mind

rather than his muscle. The applications of computer tech-

nology have reached staggering proportions and the use

of the computer is now commonly viewed in the firm-

from the largest to the smallest. The realm of applications

has evolved from the most sophisticated, scientific appli-

cations down through a spectrum of applications to the

most trivial of bookkeeping tasks. The future of the applications in business apparently is bounded only by the

imaginations of the systems analysts and designers of com-

puter activities.

One of the manifestations of the growth of computer

applications is in the area of simulation. The use of simu-

lation in the firm has become widespread. Companies have

examined the use of simulation from the point of view of

detennining the optimum number of operators in a tool

crib to problems of machine replacement and breakdown

and to the point of simulating the entire firm.

Many analysts have run into difficulty in selling the

results of a simulation exercise to top management. Per-

haps there are good reasons for management's lack of

acceptance of simulated results, but just as likely, the

credibility gap may be attributed to a rather hidden reason

instead of the obvious ones.

On the surface, managers may merely distrust the language of the computer analyst. It is alien to them and hence evokes a natural barrier. Beneath this surface distrust lies the very real possibility that the simulation itself may not be acting in the fashion that the analyst expects. It is to this particular delimited problem area that this paper is devoted.
Simulation may be defined as the process of conducting experiments on a model of a system in lieu of either: ( 1) direct experimentation with the system itself, or (2) direct, analytical solution of some problem associated with the system.1 The model is merely a representation of the actual situation or system coming under scrutiny. This may be a f(X) set of statistical distributions that represent such things as frequency of occurrence of machine breakdown or length of service required on the machine, etc. One method used in the simulation of such activities is the Monte Carlo Method, a technique with which most systems analysts have become quite familiar.

The Recursiveness Check
To determine if the random number generator has become repetitive, two tables are established. The first contains the first 100 random numbers generated. The second table contains the next 100 random numbers. The two tables are compared. If they are equal, repetition has set in. If they are not equal, the entire second table is shifted up one position and a new random number is generated and inserted at the bottom of the second table. Again the two tables are compared.

The answer, of course, depends on the compiler used. Those compilers which follow the rules of the USA Standard FORTRAN would not even compile this program. When standards are violated, we enter the gray areas of FORTRAN, where we have many pros and cons as to what a compiler should do. The results listed below indicate that mixed mode arithmetic is allowed not just by the third generation computers, but also by some first generation (small) computers. Unfortunately, not all of them agree on what method should be used to compute mixed mode expressions.

Data Project Management System Junior Version
Lutter and Helstrom, Inc., Chicago, have the availability of an assignment control system called DPMS Jr. (Data Project Management System junior version) . This system has been designed especially for the dp system/ programming group of the majority of computer installations (typically having less than 10 or 12 systems designers/ programmers on the staff) rather than the large shops.
A backlog file is maintained for each person on the staff, with job numbers, description of the job, target dates, hours estimated, revised estimates, hours spent and remaining plus percentage completion. Summary information includes total time available, assignment time spent, time unassigned, number of projects open, number of projects closed.
This simplified system was created for the smaller shops that now must accumulate statistics for the new IRS rulings.

Interactive Data Retrieval for IBM 1130
Aeronautical Research Associates of Princeton, Inc. (ARAP) has developed an interactive data retrieval program for use on an IBM 1130. It is designed to operate directly from the console or, if the 1130 is so equipped, via a remote terminal. Batch mode processing is also possible.
The program handles both the numerical and textual fields of a data bank with equal ease. Selection of a particular subset of data can be accomplished by prescribing that certain properties be "greater than," "less than," "equal," or "not equal," to some value or that they "start with," or "contain," some element.
Sorting of the selected data can be on the basis of numerical value or alphabetical order. The output of the selected and sorted subset of data can be directed to either the console, a re-

mote terminal, or a line printer. Furthermore, the particular subset items to be listed can be chosen interactively, or prestored instructions can be utilized. Complete freedom, including the insertion of global headings, local headings, date and paging, is available to the user.

FEBRUARY, 1970

A computer that can help save the

lives of policemen has been at work

for the State of Delaware for over ten

months, and has proven itself as a

tool for administration and law en-

forcement.

The computer, an IBM System/360

Model 40, is the nucleus of the

information network called DOVER

(Delaware On-Line Vehicle and En-

forcement Record system). DOVER

provides immediate information on

drivers' license records, violations, and

(

stolen vehicles for state troopers on

patrol.

Over 27,000 students at UCLA registered for spring semester classes using a new computer-based enrollment system. Of that number, 10,000 students registered "on-line" through thirty TVlike communications stations manufactured by Computer Communications, Inc.
Less than a second after the student identified himself through the communications station, his pre-registration class selection list was flashed on the screen. If all the classes the student had previously selected were available, the schedule was confirmed. If a class was filled or for any other reason not available, the student requested an alternative course through the keyboard/console. Subsequently, the computer confirmed the class selection by printing an official study list. Average enrollment time per student was about one minute.
In addition to speeding the enrollment process, the computer safeguards certain registration procedures. For example, the computer prevents a student from shopping and enrolling in several classes and deciding later which classes to discard. The computer also prevents a student from enrolling in more classes than his course limit allows. Ultimately, it is intended that the computer assign classes to rooms tailored to the enrolled number of students to make optimum use of campus space.
The enrollment system was developed by the Office of Systems and Procedures utilizing the remote console system of the UCLA Campus Computing Network.
In addition to the enrollment system, the Campus Computing Network handles thousands of different jobs weekly for UCLA and more than 100 other colleges and universities in the Western States. The jobs processed in some 20 different computer languages, touch on almost every facet of classroom instruction, scholarly research, and administration of UCLA and participating schools.
The system hardware includes forty

CC-30 Communications Stations con-

sisting of a keyboard, controller, and

television display. The multiplexer and

interface units to the IBM System 360,

Model 91, were also manufactured by

CCI.

·· ·

This visual display unit, above, with a typewriter-like keyboard is linked to a computer as part of an experimental program to improve the quality and availability of legal services to the disadvantaged.
The IBM 1130 computing system at the Dane County Legal Services Center, Madison, Wis., contains client records, interview sequences and various legal documents. Staff members use the system to interview clients and gather information on their cases. As questions appear on the screen, an operator types responses on the keyboard. The computer can display data on the screen or print it out.
The computer-based program frees attorneys from routine work to devote more time to personal consultation with clients.

Colonel Charles Lamb, Superintendent of State Police, said, "The system not only makes the trooper's job easier, it may also save his life, because he knows when he's stopping a stolen car.
"DOVER gives · us the potential to develop a centralized law enforcement information system on a computer, eliminating many manpower-consuming clerical tasks, such as those involved in tracing suspects throughout the state," Colonel Lamb said.
Using DOVER, troopers can check a vehicle's status before stopping it by radioing the license number to police headquarters. There, operators query the computer through typewriter-like terminals and relay the response to the officer. The whole process takes less than a minute.
James Deputy, State Highway Controller, whose department is responsible for the computer operation, said the system is running perfectly and is fully utilized by the Motor Vehicle Division of the State Highway Department and the State Police.
The Motor Vehicle Division uses DOVEiR to maintain three types of information: drivers' license records, including a history of violations; vehicle registration and ownership data, and the stolen vehicle file.
An added advantage of the system is better control over access to the records, Mr. Deputy said. To query the computer, one must know the proper code numbers. Also, certain information, such as the total number of violations on a driver's record, is available only to authorized personnel within the Motor Vehicle Division.
The computer also does accounting chores for the Highway Controller's office, but its speed of operation enables the police to use the system 24 hours a day with virtually no interruption of other functions.

Bisynchronous Oriented Communications System is a macro generated program designed to transmit tape or disk files over high speed lines in bisynchronous mode. The macro-generation allows the program to be self-tailoring to the constraints of the network and hardware configuration in which it is to operate. Broad flexibility is allowed in specifying the number of circuits to be controlled, the operating system, block size, etc. The program provides for statisical logging and error analysis. The operator is notified if line errors exceed a threshold value. Line utilization is (optionally) increased by extracting blanks in excess of two and restoring them at the receiving end. The program also has its own restart capability and allows for the retransmission of a single volume of a multi-volume file.

DEEP/360 is a 3K subroutine which is linked into a problem program to inhibit "data exception" type program checks. It was developed for use in testing COBOL and Assembly Language programs where data check program aborts occur often. DEEP/360 is called only twice, once at .program initialization and once at program termination. All logic spanned by these calls is protected against data exception program checks. DEEP/360 attempts to "correct" faulty data through the application of a few simple rules. Absolute addresses of instructions involved in any data error trapped are printed on the system console, and problem program execution proceeds uninterrrupted. An auxiliary package, OVRLAY2, permits usage of DEEP/36Q in COBOL overlay programs. DEEP/360 and

MASTER SHADOW I (A Remote Access,

Message-Switching System I

NI A

SHADOW is a highly-advanced communications software system for handling remote terminals under the MASTER Operating System on CDCR 3500 and 3300 Computer Systems. It serves primarily as a switching hub for communications on the CYBERNETTM network. Th is extension of operating software will hon.die a wide variety of remote job data strings. The SHADOW System will form an on-line communications link between 3300 and 6600 Centers or other 3300 Centers enabling a customer's MARCn1 Terminal to have access to 3300 processing or 6600 processing as well as to the SHAO·E file management system on the 3300. SHADOW will provide truly automatic network processing by allowing jobs entering the system to be processed at other sited.

maintenance, and efficient compilation of source language programs for da·ta processing facilities. Programmers are relieved of a time consuming and error-prone clerical activity, and computer time is saved since several programs can be entered, changed, removed, and/or prepared for compilation at once, and at computer (not programmer) speed. The program also will generate a job stream file and job control setup for compiling or assembly, and handles test files and job contr9I cards without initiating computer control oper9tions. Unusual is the generation of a Library Index report, a table of contents of the program library. Program description, version number, modification, number, date of last revision, language, author, number of statements, and number of changed statements are reported. A Report of Changes itemizes changed statements, providing a valuable historical record of all maintenance activity on a program. A Job Schedule Report, listing job control setu.ps, is produced when this facility of the program is used. PLUS

CRAM/360

$6,200

Data can now be stored on ordinary ftle

media in far less space than wQs normally

required, by using CRAM/360 Compression, Retrieval and Maintenance. CRAM/360

is capable of reducing the disk storage re-

quirements for most 360's by an average of 40% . It is easily adaptable for other manu-

facturers' machines. It requires no mainte-

nance at any time.

The system stores data in a special direct access library. The data is fragmented to optimize retrieval, as well as being cpm-

pressed on storage. When the source dota is scanned, all blanks are deleted and only

valid data is stored. Data is automatically decompressed upon retrieval. Once data has

been accessed, under one of the 1,125 reusable index pointers, it is stored on spe-

cific tracks assigned to each member of the

fragment. When data is deleted from the library, its index pointers and associated

tracks are freed for re -use. Various options are available for the user.

TELE-COBOL

$15,000

A system consisting of access methods, line handlers, and utility programs which allow an OS/360 user to receive and transmit data to remote terminals while staying within COBOL (PL/I and FORTRAN support are also available). The user writing in COBOL includes a "CALL INPUT" statement to process data received from a· remote terminal and/or a "CALL OUTPUt" statement when he desires to transmit data. The handlers will queue in.put from the terminals on a disk and notify the operator when transmissions are received and which user programs they are being delivered to. The appropriate COBOL program will be called into another partition to process all

the data accumulated f.or it. Also, there are three utility programs in the system which create, purge and dump the files, respectively.

PSI-VALET LIBRARY SYSTEM

$2,880

PSI-VALET is a totally integrated library storage, maintenance and management security system. Operating under OS or DOS on any 360 model 25 or larger, the three phase system requires 22K of memory and will run in any 22K batch partition. Any program (source or object), job control stream or card image data file may be stored, retrieved and main I a in ed. PS IVA LET, by creating a central direct access disk or ddta cell library, will eliminate card deck storage, will increase programmer and operator efficiency, project control and management security. Job stream generation with job control will better uti.lize CPU time.

PSI-VALET is designed for direct access storage devices. Storage is ran.dam and access is direct. File reorganization is never required. Spate is conserved by compressing all additions to the library. Retrievals are expanded to their original condition. All additions to the library can be sequence checked. Any library file can be transferred from one type storage device to another and be re-entered with the proper respective format. Special PSI-VALET features will aid the teleprocesser.

The PSI-VALET library system will generate a job stream with job control to compile, assemble, link edit, etc. All or any portion of the library may be reproduced on tape, printer, punch or disk. Production status programs or files cannot be modified or deleted. Modifications can be made of copied versions of production programs. Library file deletion requires management in,tervention. PSI-VALET systemizes the activities of all programmers. On line-real time programming ma intenance is possible. PSI-VALET gives management control by producing a library directory listing of all modifications and library activity, the date of activity and the status and modification number of each program and file. For management security, special back-up tapes

are produce<# which can be restored in minutes in the event of a disaster.

TESTGEN-The COBOL Test Data Generat.or

$3,000

TESTGEN is the test data generator for use with all COBOL computer programs. TESTGEN generates the right amount of data, giving sums of numbers to be checked against the program's answers. Most or all of TESTGEN's information comes from th~ source program itself,. Alphabetic, alphanumeric data are generated. You have the use of optional . co.n.trol cards to expand and restrict character sets, to have sequenced rather than· random data, and to give totals and sub-totals of numeric fields based on control breaks in other fields. Subtotals and totals may be computed for the product of two fields even though the product itself does not appear in the test data. Using TESTGEN is as simple as making an ordinary compilation. Just place TESTGEN and the COBOL source program together in the input s.tream. TESTGEN will . . . scan each File Descr~p tion analyzing the data record formats and printing any source errors recognized. TESTGEN will . . . write onto cards, tape or disk records formatted according to the specifications of the File Description in the source program. TESTGEN will . . . print listings and sum mary totals of the test data produced.

COBOL TOG TEST DATA GENERATOR $9,000
Test Data Generator automatically generates all the input files required to check out COBOL programs. Eliminates laborious and repetitive manual preparation of data for testing programs. Input data is created using the Data Division of the COBOL source program and English-like control cards. This data is then used as the foundation for testing the logic of the COBOL program. Test data inputs can be retained in the form generated by TOG for repetitive use in testing the procedural steps of the programs. Programmers can specify as many single and/or multiunit input files, in any combination, as may be required to thoroughly and properly check out a program. Different record types can be defined for a file and the number and order of records of each type can be specified, either explicitly or implicitly. Distribution of records and fields within records can be controlled. Data mixes, analogous to real-life data, can be incorporated to test and retest the logic of a new or recently modified program. TOG permits users to C:uster values of an item

THE AUSTIN S/360 LIOCS SIMULATION SYSTEM

$5,875

The Austin Simulation System allows third generation S/360 programs, under DOS to access 1400 compatibility disk files. The System allows the user to immediately write S/360 programs which will not hove to be altered once the file is converted to a native S/360 file. Sinc:e both the S/360 programs. and the unconverted 1400 programs con access the some 1400 compatibility disk file, the 1400 to S/360 conversion con take place orderly, one program at a time, and once all the T400 programs hove been converted, the system will also allow the user to physically convert the disk file in a matter of minutes. The system is easy to use, using keyword macros to describe the 1400 file and the S/360 file to which the user will eventually convert. The Simulation Sys,tem con make a 1400 Consecutive or Control Sequential file act like a S/360 Sequential or lndexSequentiol file in any combination, plus allow 1400 random files to act like S/360 direct access files. Be:ause the file definition is in the Austin module and not the problem program, the problem program will not have to be recomplied when the compatibility file is converted to the S/360 native file.

CIP is a debugging program that allows automatic debugging of multiple errors during program execution. Just as a COBOL compiler allows a user to catch multiple compilation ·errors, CIP allows users to catch multiple errors during execution. During program testing, the system intercepts any operator, program check, interval timers or unrecoverable error interrupt and automatically displays the module name and the interrupt location in both absolute and relative values. It can be used in unit testing of program modules, system testing, and recovering from software errors in the initial stages of productive system operation.

COST ALLOCATION SYSTEM

$2,000

This program reads and stores a perman.ent allocation table and uses this table to allocate input direct cost and volume items to any number of line entries for the generated report. Each of the allocated entries in turn is allocated to other line entries by repeated scans of the table until all allocations have been completed for each input item. After a sort/merge, these direct and allocated cost and volume records are then summarized and a report .printed of this month, last month, and year-to-date cost and volume data, along with cost center and line entry identification (carried on Master File record). File maintenance (add, change, delete), as well as file updating, is performed concurrently with report printing. Flexibility is achieved in report printing by use of Master File item codes to perform sign reversal, accumulation to a specified level, selected accumulator print and roll totals, and calculation of cost I quality ratios. This system was designed for cement plant cost allocation, but can be readily used without program change for any operation where "cost centers" can be logically defined.

The derivatives of this analysis are then utilized to construct a municipal market model, which fully reflects municipal market conditions as of the date of analysis. Three primary considerations of determining the yield of a municipal bond are: 1. Quality of bond; 2. Coupon; 3. Maturity. The quality of the bond (credit characteristics) varies within the popular ratings AAA, AA etc. The municipal bond pricing program allows for a wide disparity in ratings through a numbering system which provides a more refined definition of relative trading characteristics, while credit characteristics are the starting point for estimating the worth at which a bond will trade.
